Abstract: A power controlling unit for use with a radio board of a trolley pole switch controller is disclosed.  The trolley pole switch has at least one frog for switching the path of travel that  an  energy  collector  takes  through  a  junction  of catenaries.    The  power  controlling  unit  includes  three reduction stages,  a chopper control stage,  and two output stages.  A first reduction stage reduces power received from one catenary to an initial power level.  The chopper control stage outputs two pairs of alternating signals. Controlled by a first pair of alternating signals, a second reduction stage reduces the initial power level to a secondary power level to operate the radio board.  As long as it receives the initial power level, the third reduction stage reduces the secondary power level to a primary power level to operate the power controlling unit.  Controlled by a second pair of alternating signals and the initial power level, when a turn output stage receives a turn command from the radio board, it switches power from one catenary to a turn solenoid of such frog thereby switching the path of travel that the energy collector will take to a turn catenary.   Controlled by the second pair of signals and the initial power level, when a straight output stage receives a straight command from the radio board,  it switches power from one catenary to a straight solenoid of such frog thereby switching the path of travel that the energy collector will take to a straight catenary.

Abstract: A drive mechanism of a suction or deflection adjustment roll having a spur wheel gear. For a suction roll, a stationary suction box may be guided outward through the drive mechanism to be coupled with a suction device. An external gear ring may be rigidly coupled to a driven or gear end of the roll to mesh with a driven pinion. The driven pinion may be driven via a drive shaft coupled to the driven pinion through a pair of enmeshed gears. The driven pinion and an end of the drive shaft coupled to the pinion may each include a self-adjusting bearing, each self-adjusting bearing being adjacently positioned and supported on a bearing journal. The self-adjusting bearing associated with the end of the drive shaft may exhibit radial play with respect to one of an inside diameter of the drive shaft or an outside diameter of the bearing journal, which may permit tilting of the pinion with respect to the bearing journal. Force transference may be improved by positioning the pair of enmeshed gears connecting the drive shaft and pinion between the adjacent self-adjusting bearings.

Abstract: Smart cards are cards which control the execution of their own transactions, so as to avoid providing specialised card readers for each type of transaction. The smart card system of the invention has at least one card reader (1) and a smart card (4) storing a transaction management programme. The system is characterised in that the reader (1) controls the exchange cycles by alternately and repetitively sending to the card (4) a request for issuing an instruction and data packet designated as "card message", and a report statement associated with a report message relating to the execution of previously received instructions in card messages by the reader. The smart card (4) controls the processing cycles which are synchronous with the exchange cycles through transaction management programme execution means which develop the instructions and data of the card messages at the rate of the card message issue requests and of report statements transmitted by the reader (1).

Title: Electronically controlled carburetor
Inventor: CARPENTER TODD L
IPC: F02M7/23
Filed: 1997-12-12
Granted: 2001-05-08
Abstract: The present invention involves a carbureted fuel system for an internal combustion engine for small utility implements. The engine includes a crankcase with a cylinder bore. The crankcase rotatably supports a crank shaft having a flywheel and a magnet disposed on an outer periphery of the flywheel. The crankshaft is also connected to a reciprocating piston disposed in the cylinder bore. A cylinder head is attached to the crankcase over the cylinder bore, and a carburetor is disposed on the cylinder head. The carburetor is in communication with a fuel supply and an air inlet. The carburetor includes a mixing chamber in which the fuel and air are mixed together and then introduced into the manifold and eventually into the cylinder via a valve for combustion therein. In communication with the main passage of the carburetor is a secondary air inlet in which is disposed an air bleed device, such as a solenoid or PZT operated actuator, which is controlled by an electronic control unit. An induction coil is disposed adjacent the flywheel and is coupled to the electronic control unit so that the rotation of the flywheel generates a pulse on the induction coil that is processed by the electronic control unit. Based upon the information derived from the electrical pulses generated by the induction coil, the electronic control unit activates the air bleed device to enrich or enlean the air-to-fuel mixture fed into the cylinder for combustion. In this manner emissions associated with the operation of the engine may be reduced.

Title: Oil/water separator
Inventor: STOWELL JAMES RICHARD GEORGE
IPC: B01D17/028
Filed: 1998-10-30
Granted: 2004-03-02
Abstract: An Oil/Water Separator apparatus includes a portable container advantageously having rigid sides, including spaced apart side walls and rigid floor. Within the rigid container are defined at least two, advantageously, three chambers in an adjacent array in a downstream direction. The chambers are separated by rigid separating partitions or baffles rigidly mounted to, so as to extend between, the opposite side walls of the container.  Adjacent chambers are connected in fluid communication therebetween so that influent water containing oil to be separated may enter into a first upstream reservoir chamber. The influent water is deposited into the reservoir chamber. A downstream partition or baffle separates the reservoir chamber from the downstream coalescing chamber. The first partition has an opening under a lowermost edge thereof. Water passes under the partition from the reservoir chamber into the coalescing chamber. In the coalescing chamber, mounted in the water flow path, is a coalescing pack releasably rigidly mounted between the partition and a weir partition rigidly mounted to the floor. Emulsified oil within the water flow coalesces within the coalescing pack and is separated as oil droplets flow upwardly to the water surface within the coalescing chamber. The water flow leaving the coalescing pack is directed downwardly so as to pass into conduit passing over or through a downstream weir partition so as to flow into an outlet chamber.

Abstract: L'invention porte sur un procédé et un dispositif accroissant le débit de données et basés sur une diversité d'antennes utilisant plusieurs antennes d'émission. Un ensemble de binaires d'un signal numérique sert à produire un mot de code (106). Les mots de code sont établis en fonction d'un code de canal. Des éléments retardateurs (110) peuvent être placés dans les canaux de sortie des antennes ou moyennant une structure adéquate des codes, il est possible de se passer de ceux-ci. n signaux représentant n symboles de mots de code sont émis sur n antennes différentes. Au niveau du récepteur, on utilise un décodage ESVM (310), ou d'un autre type, pour décoder la séquence de bruit reçue. L'émission en parallèle ainsi que le codage des canaux permettent, par rapport aux techniques actuelles, un accroissement du débit des données et leur restitution même en cas d'évanouissement. Le codage des canaux peut être concaténé avec des codes de correction d'erreurs dans des conditions appropriées.
